Question

read the paragraph.
people tend to adopt the style of writing and speaking that they read the most. if hours of each day are spent absorbing the casual banter of social media, the readers own language will reflect that casual style. if this material is balanced with more serious content, such as newspapers, journals, or classic novels, the readers language is likely to reflect the depth and maturity of these sources. students should strive for such balance, regularly immersing themselves in text that is more intellectual than a passing tweet.
what central idea is explicitly stated in the paragraph?
social media is becoming increasingly popular with students.
the language of newspapers is well researched and clever.
students language is a reflection of what they read.

The central idea is that one’s language reflects their reading material.
